Modern semiconductor chips offer a FPGA, A Hard Microcontroller and a programmable Analog circuitry all integrated on a single chip, which gives the system designer a full featured, easy-to-use design and development platform where all the units are programmable and under full control of the designer, Combining this state of the art silicon chip with a Real Time Operating Systems (RTOS) gives an Engineer full power and all degree of freedoms to design end-use applications with an unparalleled performance characteristic as far as speed, Security, Simplicity, Flexibility and reliability is concerned. In this paper we described the porting experience of a Real Time Objected Oriented Dependable Operating Systems (RODOS)[1] on a mixed signal FPGA chip.
